Abstract

According to an automatic tool changing system of manipulator, a tool changing manipulator is driven to do swiveling motion and plugging-unplugging motion by a group of cam mechanism, and a tool loosening mechanism of a main shaft is driven by a system of oil pump, oil pipe, and oil cylinder to realize the coordination of the tool loosening-drawing action of the main shaft and the action of the manipulator. The whole process can be finished in only one start-stop action of the tool changing manipulator, and the tool changing speed is accelerated. But hidden trouble of damaging the tool changing mechanism exists in the system of oil pump, oil pipe, and oil cylinder, because the tool loosening-drawing action of the main shaft is not in place due to trace leakage of oil and change of temperature. According to the invention, the safety and the reliability of the whole tool changing process realized in one start-stop action of the tool changing manipulator are ensured by adding an oil supplementing hole on the oil pump, an oil supplementing cup, a tool loosening displacement detecting and alarming device, and a corresponding program of a numerical control system. The system of the invention is suitable for various kinds of main shafts by adopting normal tool loosening oil cylinder; the structure of the tool changing manipulator is simplified, and the volume is reduced by integrating a tool loosening cam with an arm swiveling cam, and the automatic tool changing system of the manipulator is further suitable for multiple machining centers such as vertical type and horizontal type.

Description

technical field [0001] The invention relates to an automatic tool changing system for a machining center, in particular to a tool changing system which utilizes a cam to realize coordinated control of manipulator and spindle loosening and broaching during the automatic tool changing process, and belongs to the technical field of metal cutting machine tools. Background technique [0002] Invention patent ZL200810011687.3, the name of the invention is: hydraulic cam linkage tool change mechanism of machining center, which proposes a manipulator automatic tool change mechanism different from the traditional technology. According to the traditional technology, the tool changer manipulator only undertakes the actions of turning the tool back and inserting the tool. During this process, it needs to cooperate with the spindle loosening and broaching mechanism. The two mechanisms need to be detected and coordinated by the CNC system. The manipulator needs to be started and stopped 3...
